A: 8
B: 9
C: 10
D: 11
举一反三
- 循环后count的值是什么? （ ）int count = 0;do { System.out.println("Welcome to Java"); count++;} while (count A: 10 B: 11 C: 9 D: 8
- 下列程序打印( )次“Welcome to Java”？[br][/br] int count = 0; do { System.out.println("Welcome to Java"); count++; } while (count < 10);
- 给定一个Java程序的代码如下所示，则编译运行后，输出结果是 ( )。 public class Test { int count = 9; public void count() { System.out.println("count=" + count++); } A: blic static void main(String args[]) new Test().count(); new Test().count();}} B: count=9 count=9 C: count=10 count=9 D: count=10 count=10 E: count=9 count=10
- 下面的代码段执行之后count的值是什么( ) int count = 1; for(int i = 1; i <= 5; i++) { count+= i; } System.out.println(count); int count = 1; for(int i = 1; i <= 5; i++) { count+= i; } System.out.println(count);
- The output of the following code is ____.<br/>count = 1; /* initialize count */ while (count <= 10) { printf("%d ",count); count++; /* increment count */ } A: 1 1 1 1 1 1 1 1 … B: 1 2 3 4 5 6 7 8 9 C: 1 2 3 4 5 6 7 8 9 10 D: 1 2 3 4 5 6 7 8 9 10 11

写出下列程序的输出结果 public class Test { public static void main(String[] args) { Count myCount = new Count(); int times = 0; for(int i=0;i<100;i++) increment(myCount , times); System.out.println(“count is” + myCount.count); System.out.println(“time is”+ times); } public static void increment(Count c , int times) { c.count++; times++; } } class Count { public int count; Count(int c) { count =c; } Count() { count =1; } }

下列程序的运行结果是（）。 public class Test public static void main ( String [ ] args ) int count = 0 for( int i = 1 i < 5 i = 2) for( int j = 1 j< = 10 j = 3) count System .out .print (count ) _

以下循环的执行次数是 count=0while count＜=10:print（“Programming is fun!”）count=count+1（） A: 0 B: 10 C: 11 D: 死循环

代码中myCount.count的值为（A）?public class Test { public static void main(String[] args) { Count myCount = new Count(); int times = 0; for (int i=0; i<100; i++) increment(myCount, times); System.out.println("myCount.count = " + myCount.count); } public static void increment(Count c, int times) { c.count++; times++; }} class Count { int count; Count(int c) { count = c; } Count() { count = 1; }} A: 101 B: 100 C: 99 D: 98
